MATLAB libraries in Mac OSX

Hello i would like to use the program Amira for the analysis of NMR data. The goal is to draw ROIs with amira, save the data as *.mat file and import the data back to MATLAB. To save data as *mat file, Amira needs to have access to the MATLAB library. In order to provide access to the library, the online help of Amira suggests the following action:

"On Mac OS X, the AMIRA_LD_LIBRARY_PATH environment variable should be set to MATLAB_INSTALLATION_PATH/bin/maci (for instance: /Applications/MATLAB_R2008b.app/bin/maci) "

Unfortunatelay, even after setting the AMIRA_LIBRARY_PATH environment variable to the installation path (/Applications/MATLAB_R2010a.app/bin/maci), saving Amira data as *.mat file results into the error:

"Trying to load the Matlab engine ... Couldn't open libmat.dylib: dlopen(libmat.dylib, 9): image not found Couldn't open libeng.dylib: dlopen(libeng.dylib, 9): image not found Loading failed, unable to open the following Matlab libraries: libmat libeng The required Matlab libraries need to be in your LD_LIBRARY_PATH. Please fix this and restart Amira."

After using export LD_LIBRARY_PATH=/Applications/MATLAB_R2010a.app/bin/maci

the error message changes into

"Saving '/Users/home_one/Desktop/data_TMP-labels.mat' (Matlab mat-file format) Trying to load the Matlab engine ... Couldn't open libmat.dylib: dlopen(libmat.dylib, 9): Symbol not found: _miFtell64 Referenced from: /Applications/MATLAB_R2010a.app/bin/maci/libmat.dylib Expected in: /usr/lib/libmx.dylib

Couldn't open libeng.dylib: dlopen(libeng.dylib, 9): Symbol not found: _miFtell64 Referenced from: /Applications/MATLAB_R2010a.app/bin/maci/libmat.dylib Expected in: /usr/lib/libmx.dylib

Loading failed, unable to open the following Matlab libraries: libmat libeng"

I even tried to change the DYLD_LIBRARY_PATH variable, but this only results into a malfunction of Gimp.app

Does anyone have a clue what is going wrong here?

run a

 system('env |sort')

from matlab and post the result

Amira seems to assume 32-bit MATLAB, but maybe you are running the 64-bit version? R2012a was a transitional release, one of the few Mac releases available in both 32-bit and 64-bit varieties. R2012b and later are all 64-bit only.
